[Paraview] Fwd: Gradient of Unstructed dataset

[Masaaki SHOJIMA]

Hi, Michael,

I found a web-page regarding the CGNS reader, in which you are making
important comments.
http://comments.gmane.org/gmane.comp.science.paraview.user/23957

I have to wait for the next version, is it right?

Thanks

Masaaki
